    Has anyone repaired a corrupted bios?

    I believe @Tailsnic Retroworks had a GNET board with a corrupted BIOS, but I'm not sure if he was able to get it going.

    Kolibri is the finest hummingbird shooter on the 32X!

    FOUND Cosam the great bare Neptune genesis 32x board.

    Yep, that's it exactly. And it eliminates all the video interference you get with a normal 32X and the passthrough video cables.

    M92 RAM (Irem Skins Game ) Errors

    Check the pins on the large GA21 SMD custom chip on the right side of the board as well - it drives the RAM chips, and you may have a pin or two loose. https://shootthecore.tech/repair/repair-log-irem-m92-arcade-pcb/

    FS SOLD - ZPF - new MegaDrive hori shmup

    FWIW, the Shmups forum feedback picture that strikers1945guy posted in his original post that mentions me is legit - I bought a $2000 Cave board from him over a year ago, and it arrived safely, promptly and matched all his descriptions. I sincerely hope this latest transaction comes through for...

    M92 RAM (Irem Skins Game ) Errors

    5.22V is way too high. Dial it down to 5.0V and retest. I never exceed 5.15V on any board if it all possible.

    M92 RAM (Irem Skins Game ) Errors

    Check your voltages for 5.0V. If the board isn’t receiving sufficient power from the power supply then it will definitely cause random RAM errors. Those boards tend to draw more power than your average board too in my experience.

    WTB plastic covers for exA boxes.

    Reporting back on using Namcot Famicom game cases for storing Exa Arcadia games. Can’t say I can recommend them for two reasons: 1) The cart is too small to fit the holders inside the case so it’ll just bang around inside. 2) When the case is closed the “Namcot” manual holder will press down...

    Clutch Hitter - System 18 issues

    If you're sure that the main board is faulty then the cause could be many things. Try probing the graphics RAM from underneath the board with a logic probe and see if there's any stuck or floating logic lines. Start with IC33, 34, 35 and 36. Also check for loose legs on the 315-5362 custom...

    Dogyuun (korea) strange audio problems

    The symptoms you describe make me think one of the address lines for the ROM that stores the sound samples isn't functioning. Could be a broken trace or corrupted ROM. The ROM is labeled "22" and is located at position A5 on the board - check it for broken traces.

    Clutch Hitter - System 18 issues

    Try dumping all of the ROMs and compare them to MAME. One or more of the graphics ROMs may be corrupted.
